Abstract: A polyamide/polyurethane composite filament yarn, which filament comprises a polyamide sheath component and a polyurethane eccentric core component exposed with a neck portion of uniform width on the surface of the filament, is manufactured by a process comprising inserting, immediately before extruding from a spinneret orifice, a molten polyurethane flow obliquely from upwards and incorporating said polyurethane flow eccentrically into a molten polyamide flow flowing down in said conduit, while a small part of said polyurethane flow radially projected in a restricted width penetrating through the thinnest portion of said polyamide flow flows down along the inner wall of said conduit. For this process, an employable spinneret comprises a leading duct for polyamide connecting to an orifice via a vertical conduit, another leading duct for polyurethane connecting to an injection pipe obliquely extending therefrom, protruding into said conduit, opening immediately before said orifice and having a slit extending longitudinally at the under side along the entire protruded length.

Abstract: In a self-alignment type-lateral bipolar transistor and a manufacturing method thereof, the base width is determined not by the image resolution limit of the lithography technique, as in the prior art, but by the impurity diffusion from the polysilicon layer 118. Therefore, the self-alignment type lateral-structure pnp bipolar transistor and the manufacturing method permit the base width to be as small as possible, resulting in improvement of frequency characteristics, and reducing the size of the transistor element.

Abstract: The invention relates to an apparatus for continuously feeding chippers with pieces of wood of approximately equal length. It consists of a grooved trough which leads into the chipper and behind which is arranged a loading magazine aligned therewith. In said loading magazine, the wood pieces are formed into compact stacks, which are then cyclically pushed into the chipper by a pushing plate. To move the pushing plate beyond the wood stack placed ready in the loading magazine on its return travel, it is mounted, according to the invention, pivotably on a support which can move back and forth, parallel to the ground, beyond the grooved trough and loading magazine. Control members provided on the pushing plate ensure, at the beginning and end of the return movement in brief cooperation with stationary control paths, the pivoting of the pushing plate into its return or pushing position. In addition, it is possible to insert between the grooved trough and chipper a closing slide which closes the chipping chamber during the final chipping cycle and serves as an additional pressing element for the wood stack during the preceding chipping cycles. …<IMAGE>…

Abstract: A robotic controller or similar machine represents the shape of an object as a hierarchy of bubbles. The position and radius of each of the bubbles is determined by first calculating the coordinates of the medial axis of the object and then creating a hierarchy of sbubbles all of which are disposed on the medial axis. The bubbles may be generated using a top-down algorithm which sequentially places bubbles around portions of the object represented by sub-divisions of branches of the medial axis. Alternatively the bubbles may be placed by using a bottom-up algorithm which combines the smallest of a large number of bubbles centered on the medial axis with its smallest neighbour to generate successively higher level bubbles in the hierarchy.

Abstract: The present invention relates to a technique which provides swift and easy error correction and detection on one or more fault-tolerant redundant storage devices (22,23). In the present technique, an information packet including (a) the destined storage location identifier in a first section (30), (b) the information in a second section (32), and (c) a unique monotonically increasing number in a third section (31), is sent by a processor (11) to one or more redundant storage device controllers (20,21) for storage in relative locations of the redundant storage device(s), where the monotonically increasing number is incremented and applied to each sequential information packet to be stored on the redundant storage device(s). When relative storage locations of the redundant storage device(s) are subsequentiy read and the information is found not to match, an error has occurred on one of the storage device(s), and if the storage location identifier on the compared information packets are also found not to match, then the information packet including the correct storage location identifier is used. However, if the storage location identifiers are found to match, then the compared information packet with the higher monotonically increasing number is deemed to contain the correct information.
